Vol 2 Chapter 1223: New idea of return landing technology

This was the result he had been waiting for for a long time, and now there was finally a response, how could he be unhappy. You know, they have relatively large restrictions on carrying out related projects. Once more restrictions are opened up, it means that they can work in more fields, thereby promoting development and progress in the aerospace field.
In addition, once the official order is obtained, the huge investment in the early stage is not a problem for them.
After chatting for a few more words, Chen Guangping immediately changed the subject and asked: "Why, Xiao Wu, I heard that on your aerospace technology side, the recent projects are progressing well.
What's the matter, give me an introduction. "
Hearing what Chen Guangping said, Wu Hao's face immediately showed a smile, and then he laughed and joked: "I said Chen Chu, you are doing a good job in intelligence work, what's the matter, you have done this before."
Go, you kid don't tease me. No one can hide anything from you. Hurry up and tell me that I am also very interested in your projects. Chen Guangping showed the tone of a crowd eating melons
Yes, since they have asked, he can't help but say, who makes this the immediate leader?
So after sorting out his thoughts a bit, Wu Hao immediately said: "This year there are several projects that are progressing well. I will not introduce the Oasis One inflatable space experimental module and our Oasis Farm project.
Let me first report to you the latest progress we have made in the field of rocket technology. First of all, you should know that we have completed the off-site return, landing and recovery experiment of the Jianmu-2 first-stage rocket this time and achieved complete success.
In addition, the air hoisting and recycling technology of our Jianmu-2 rocket's fairing has been verified again and has also been successful, which is sufficient to prove the reliability and safety of these two technologies. "
"Well, it's true. The leaders also said at today's meeting that you are really doing very well in the rocket's return and landing recyclable technology. The leaders also asked the relevant departments to put down their shelves and humbly want you to learn." Wu Hao As soon as the words fell, Chen Guangping replied on the phone.
Where is it that we should learn more from the national team, we still have big shortcomings. Wu Hao quickly replied.
Don't be so pretentious, you also have a lot of merits, and this is worth learning. So, we are learning from each other and improving each other. Chen Guangping said with a smile.
Haha, Wu Hao smiled, and did not continue to be polite in this regard, and then continued to introduce: "The most important thing for the launch and recovery mission of the Jianmu-2 modified rocket is the second-level rocket body of the Jianmu-2 modified rocket. The apex of re-entry into the atmosphere returned to the landing experiment.
This experiment is very difficult and risky, and it is not easy to achieve such good experimental results.
From the relevant analysis reports we have obtained so far, the results of this experiment have far exceeded our expectations.
This also makes our scientific research and technical team have a new idea in the recovery technology of the secondary rocket. "
Oh, it seems that I have gained a lot. Let me talk about it, I also discussed with some experts yesterday, and they have a high evaluation of your experiment. Chen Guangping said with interest.
Wu Hao nodded and said: "Okay, our scientific research and technical team has recovered the wreckage of the secondary rocket body that returned to the ground. After the first round of inspection, we got some surprising preliminary results.
First of all, the burning state of the rocket wreckage is good. In addition to the melting of the special insulation coating on the rocket body surface, the surface of the rocket body is in good condition. This shows that the performance of our new special insulation coating is very excellent. It also shows that our atmospheric loading technology is also very reliable at first glance. "
Hearing his words, Chen Guangping also revealed a pleasant tone of surprise: "It seems that your special insulation coating technology does perform very well. This is indeed good news.
In this way, you go back and ask someone to prepare a detailed report on this special insulation coating technology and the performance of this new special insulation coating in this experiment, and then submit it.
I will take a look first, and then submit it for you. If this new type of special thermal insulation coating is really excellent as you said, I believe it will have results soon. "
Thank you, Chief Chen. Wu Hao thanked him, and then continued: "Secondly, our flying wing gliding and multi-parachute deceleration technology performed very well in the experiment. The body of a second-level rocket fell to the ground and the speed was already very low. , So the wreck is very intact and the damage is not too serious.
I think in the next step, we can watch the safe landing experiment of the second-stage rocket. "
That's pretty good. Chen Guangping smiled and asked, "Do you have new ideas about this safe landing technology, or stick to the original technical ideas."
Wu Hao smiled and nodded: "I have a new idea. Based on the results of this experiment, I plan to use the rocket engine ignition reverse thrust landing technology of the first-stage rocket body in the landing technology. UU看书www .Uukanshu.com
When the secondary rocket decelerates layer by layer and reaches a suitable speed, the last set of parachutes will be thrown, and then the rocket's attitude will be adjusted quickly and further slowed down.
At the same time, the tail engine of the second stage rocket will also re-ignite, thereby further decelerating, allowing the rocket to land safely and smoothly. "
Hearing his introduction, Chen Guangping was silent for a while on the phone, and then returned: "In this case, the entire recycling method and technology will probably be more complicated. Can it be done? Don't make it hard. Put so much money. Throw it in, and in the end it was all washed up. This is costly and time-consuming."
Chen Guangping’s concerns are not unreasonable. This method of recovery and landing is indeed more complicated, with higher technical requirements and greater difficulty. So whether it can succeed or not is still unknown. Don't invest so much money in that time, but in the end it fails. This is not just a waste of money, but a waste of time.
And compared to money, time and development cycles are wasted, which is really not worthwhile.
Wu Hao nodded when he heard the words: "You are right. We are not sure about this recovery landing method and technology. However, it is precisely because we are not sure that we will actively explore.
Compared with investment, I am more optimistic about the huge benefits brought by the successful return and landing technology. This is not only economic, but also other aspects.
In addition, we are also a commercial company, and we must think twice about every investment. It is impossible to say that we will spend a lot of money on a technology so endlessly, which is not worth the loss for us.
After all, this project is just one of our many aerospace projects and even rocket technology projects. It is impossible for us to delay the development of our other projects for it. "
